Title: A surgical stapling instrument
Inventor: BABKIN SVIATOSLAV IVANOVITCH
IPC: A61B17/128
Filed: 1959-09-02
Abstract: 910,148. Stapling-machines. RESEARCH INSTITUTE OF EXPERIMENTAL SURGICAL APPARATUS & INSTRUMENTS. Sept. 2, 1959, No. 29913/59. Class 89 (3). [Also in Group VI] A hand stapling machine for ligaturing blood vessels with metal staples comprises a hooked jaw 11 for reception of a blood vessel, a staple magazine 15 slidable along the instrument towards the jaw by moving a first handle 39 on a push-rod 37 towards a second handle 12, continued movement of the first handle causing a pair of staples to be driven out of the magazine to engage inclined recesses 14 in the jaw and to be bent thereby to encircle and ligature the blood vessel. The body 10 of the device carries a hooked jaw at one end and the second handle 12 at the other, the push-rod 37 being slidable towards the jaw against a spring 40 within the body 10. The magazine has a pair of transverse lugs 18, 19 each having a U-shaped slot 20, 21 which receives staples. The staples are fed transversely one at a time from each slot into two parallel staple guides 16, 17 by staple feeders 22, 23 operated by leaf-springs 25, 27. Staple drivers 29, 30 are connected for movement with an actuating rod 31 in the magazine. The actuating rod 31 is screwed to the push-rod 37. In use, projection of the push-rod first moves the magazine into engagement with the blood vessel in the crook of the jaw 11 and then projects the actuating rod 31 and staple drivers 29, 30 relative to the magazine against a second spring 35, so that the staples are forced out of the guides 16, 17, engage the recesses in the jaw and are bent into triangular form around the blood vessel. A lug 42 on a leaf-spring 41 fixed adjacent the first handle 39 permits only limited relative movement between the handles until the lug is depressed, thus preventing accidental discharge of the staples.

Title: Connector
IPC: H01R13/193
Filed: 1972-06-27
Abstract: 1395601 Releasable fastenings RAYOHEM CORP 27 June 1972 [29 June 1971] 30066/72 Heading E2A [Also in Division H2] A connector comprises two or more resilient jaws 51, 52 encircled by a collar 55 of a heat recoverable metal. The internal dimensions of the collar are smaller than the external dimensions of the jaws when both members are in their unstressed states. Originally the collar is cooled to -40C and forced onto the jaws. At this temperature the collar is in a martensitic state and is expanded by the jaws. At room temperature the collar is in an austenitic state and recovers its natural dimensions, thus compressing the jaws, against their resilence, onto an inserted male member (not shown). The connector may be heated and cooled repeatedly to seize and release the male member. The collar expands and contracts 6-8%, but the jaws act as levers to increase the movement at the contact points 53, 54, or in alternative embodiments to reduce the movement. In other embodiments the jaws are rigid, hinged and resiliently biassed by a spring or a hydraulic system. In other embodiments the heatrecoverable member is inside the resilient member, and expands on warming to force the resilient member to fit tightly inside a ring. Particular heat recoverable alloys are specified including alloys of specified proportions of Ti and Ni with small amounts of Fe or Co. Specific dimensions of one embodiment are given. Reference has been directed by the Comptroller to Specification 1203276.

Title: A process of providing a cutting tool with a hard metal working surface
IPC: C23C16/32
Filed: 1958-09-23
Abstract: In a process for providing a cutting tool with a hard metal working surface, tool metal is heated in a chamber to a temperature at which tungsten carbonyl thermally decomposes, hydrogen is passed through the chamber to remove the air, and the tool metal is then contacted, at sub-atmospheric pressure, with tungsten carbonyl whereby tungsten carbide is deposited on the tool metal.  Depending on the pressure, up to 10% of tungsten may be co-deposited.  Deposition may be effected directly on to the tool itself, with appropriate masking, or on to a shaped section which is subsequently secured to the tool shank.  Metals on which the tungsten carbide may be deposited are steel and copper- and nickel-coated base metals.

Title: Method for removing material from plastics
IPC: H05K3/00
Filed: 1965-07-16
Abstract: 1,089,285. Electron beam machining apparatus. K. H. STEIGERWALD G.m.b.H. July 16, 1965 [July 24, 1964], No. 30289/65. Heading H1D. In a method of perforating plastics by means of an electron beam, e.g. for making gaspervious plastic foils, the plastics material is exposed to energy before the machining operation proper, to stiffen its surface and so prevent any deformation of the surface during machining. The energy may be supplied by contact with a hot medium, by electromagnetic radiation, or by irradiation with a defocused electron beam. In the latter case, machining may be effected by a beam having a central focused portion and a surrounding defocused portion which irradiates the vicinity of the hole next to be bored, or use may be made of a separate electron beam. Alternatively, stepped pulses are applied to the control electrode of the beam generating system, the first part of each pulse producing a defocused beam, and the second part a sharply focused beam for machining. By machining with a beam having a higher intensity than would be necessary for perforation alone, the material surrounding each bore may be sufficiently stiffened for further holes to be bored therein without any additional exposure to radiation. As described, the beam generating system comprises two sets of deflection coils (8), (13), Fig. 1 (not shown), with an intermediate focusing coil (11) and a transversely movable diaphragm (10) and a plastics foil is moved under the beam between drums.

In an arrangement in which a three-limbed core 8, Fig. 2, is provided with a divided yoke at one or both ends, the auxiliary winding 7 is located on one of the yoke parts. In an arrangement comprising a five-limbed core, Fig. 3, the auxiliary winding 10, 11 is arranged on one or both of the normally unwound outer limbs. In both these arrangements, a short-circuited or squirrel-cage winding 9 or 12 is provided to ensure subdivision of the auxiliary flux. The auxiliary winding may be excited from separate exciter windings on the core limbs or it may be connected across appropriate points on the main winding which may be star, delta, or zigzag connected. These points may be selected to give a 30‹ phase displacement between the auxiliary flux system and one phase of the main flux system to-effect suppression of 5th and 7th harmonics. Alternatively, a first auxiliary winding 19 on a subdivided yoke at one end of the core may be connected to the main windings 28 as shown in Fig. 6, to produce an auxiliary flux 20‹ phase displaced from one phase of the main flux-system, in which case a second auxiliary winding 24 is provided as shown on a limb of the subdivided yoke at the other end, whereby the 11th and 13th harmonies also are balanced out.
